The Alpina B3 Cabrio (E93) has a curb weight of 1845 kg (around 4068 lbs). This weight is relatively substantial for a two-door convertible, stemming from Alpina's performance upgrades and luxury-focused components. The weight influences the car's handling characteristics by providing stability at high speeds, though it may slightly reduce agility compared to lighter sports cars. However, careful suspension tuning balances comfort and sporty dynamics, making the weight acceptable for the driving experience Alpina aims to deliver.

With a length of 4580 mm (180.3 inches), width of 1782 mm (70.2 inches), and height of 1395 mm (54.9 inches), the Alpina B3 Cabrio (E93) generally fits comfortably into a standard residential garage, which typically measures about 2400-2700 mm (94-106 inches) wide and 4800-6000 mm (189-236 inches) deep. Its width and length are well within typical garage dimensions. Still, drivers should consider space for opening doors and additional clearance around the vehicle when parking indoors.

When the rear seats of the Alpina B3 Cabrio (E93) are folded down, the luggage capacity expands to approximately 430 liters (about 15.2 cubic feet). This additional cargo space enhances practicality for carrying larger items or increased luggage loads, especially useful during longer trips when more storage is needed beyond the standard trunk space in a cabriolet.

The Alpina B3 Cabrio (E93) is equipped with front tires sized 245/40 R18ZR and rear tires sized 265/40 R18ZR. These sporty, wide tires provide excellent grip and handling characteristics, supporting the car’s performance-oriented nature. The staggered setup (wider rear tires) helps improve traction during acceleration and enhances cornering stability, contributing to a dynamic and confident driving experience characteristic of Alpina-tuned BMW convertibles.

At 1395 mm (approximately 54.9 inches) tall, the Alpina B3 Cabrio (E93) sits lower than many standard cars but aligns with typical sports convertibles' low-profile design. This reduced height helps improve the car’s aerodynamics and center of gravity, which aids in sharp handling and a sportier feel on the road. It also accentuates the sleek and elegant styling expected from a premium cabriolet.

Compared to its predecessor based on the BMW E46 platform, the E93 Alpina B3 Cabrio is larger and somewhat heavier. The E93 measures 4580 mm in length and weighs 1845 kg, whereas the E46 Cabrio was generally shorter and lighter. This increase is due to evolving safety standards, added luxury features, and performance enhancements that Alpina integrated. While slightly heavier, the E93 benefits from improved chassis rigidity, modern technology, and more powerful engine options, overall enhancing performance and occupant comfort.

Among luxury convertibles produced during 2007-2012, the Alpina B3 Cabrio (E93) fits comfortably in the compact executive segment, comparable to models like the Audi S5 Cabriolet and Mercedes-Benz C-Class Cabriolet of that time. Its length of 4580 mm and width of 1782 mm offer a slightly sportier and lower profile compared to bulkier models, but with an emphasis on performance. Its weight at 1845 kg is competitive, reflecting a good balance of sportiness and luxury, with Alpina’s tuning ensuring engaging driving dynamics within this peer group.

The Alpina B3 Cabrio (E93) has a maximum allowed weight of 2200 kg (approximately 4850 lbs). This maximum weight includes the vehicle’s curb weight (1845 kg), passengers, cargo, and any additional equipment. This means the car can safely carry an extra 355 kg (about 783 lbs) of combined load. Understanding this limit is important to avoid overloading the vehicle, which can negatively affect handling, braking, and tire wear, as well as overall safety.

With a width of 1782 mm (70.2 inches) and length of 4580 mm (180.3 inches), the Alpina B3 Cabrio (E93) is moderately sized for a luxury convertible. Its dimension makes it relatively easy to maneuver in urban settings compared to larger luxury vehicles or SUVs. However, the width requires some care in tight parking spaces. The length supports cabin comfort but may pose challenges in very compact spots. Overall, its dimensions balance driver comfort and agility, making it suited for city driving, especially with the agility enhancements typical of Alpina models.
